NORTH West has taken the stage with her superstar dad Kanye in South Korea.

The concert performance comes after North's mom Kim Kardashian, 43, was reportedly alarmed by her ex-husband's behavior.

On Friday, North, 11, joined Kanye, 47 as he performed tracks from his collaborative albums with Ty Dolla $ign, Vultures 1 and 2, and many of his other hits in South Korea.

The show was live-streamed to Kanye's YouTube account, where fans back in the States and around the world watched the Yeezy founder and his preteen daughter be cheered on by thousands of fans inside the Goyang Stadium in Seoul.

Kanye donned all-white, while North who danced and rapped alongside her father sported all-black attire.

North's on-stage appearance comes after reports that Kim Kardashian has become increasingly worried about her four children spending time with their father, Kanye.

The reality star, 43, is concerned about what their kids North, Saint, 8, Chicago, 6, and Psalm, 5, are “exposed to” around their rapper dad and his new wife Bianca Censori, claimed a friend of the Skims founder.

“Kim is constantly getting more and more alarmed about the stories she sees coming out about Kanye and Bianca,” said a source close to the reality TV star.

“Every week it’s something different and she fears it's no longer a healthy environment for the younger kids to be in.

“It’s not like she’s even in contact with Kanye directly - they either speak through nannies, [her mom] Kris or lawyers - but North sends her pictures and videos when she’s with her dad.

"It’s like Kim wants to see with her own eyes what’s going on - she’s saying she wants a sit-down meeting urgently with both of them to discuss co-parenting and put some new ground rules in place."
